Start with the job description
Highlight repeated skills, tools, and certifications in the posting. These are your priority keywords — not every word, but terms that appear in requirements and responsibilities.
Place keywords where ATS looks
Skills section, summary, and recent role bullets carry the most weight. Use exact phrasing when accurate (e.g. 'Project Management' vs 'PM').
Pro tip
Run ATS Checker against each posting to see missing keywords ranked by impact.
